Sawakaze (a Touhou LW original) refers to a breeze near a mountain stream. This is the temperament of Nitori, who works behind the scenes to prevent her rival from monopolizing the market. Nitori is endowed with Water Phase as she hides beneath the water's surface and Moon Essence with her skillful two-faced dealings. The flexible and patient Water Phase resists Metal Phase, because metal collects water, but it is weak to Earth Phase, because earth directs water. The cooperative and indecisive Moon Essence resists the alluring and arrogant Sun Essence, but it is weak to the diverse and uncooperative Star Essence.

The ability of Nitori Kawashiro from the world with a black market. There are no noticeable differences between this ability and that of other Nitoris. The disturbance caused by Chimata Tenkyuu's ability had many long-lasting effects on Gensokyo. Perhaps the most notable was that it directly led to the black market trading of Ability Cards. Thanks to Marisa's investigation, aided by Chimata's careful observance and Nitori working behind the scenes in opposition to the very idea of black markets, the mastermind was revealed to be a certain yamawaro. When everything came to a close, it was decided that the yamawaro's plans were nothing more than a clever business venture... or at least, that's how it was meant to go. Markets naturally arise when groups of intelligent beings gather together. Like humans, youkai have their own civilization. While it is predominantly spiritual and magical, they have developed economically, too. Most youkai live far longer than humans, so their sensibilities and views of the world are completely different. However, that doesn't necessarily mean they disagree on everything. Since youkai are forced to rely on humans for their mental and spiritual needs, they can surpass humans in academic, artistic, and cultural pursuits fueled by the spirit. For example, kappa excel at engineering, oni at architecture and construction, and magicians at natural philosophy (called spirit magic among youkai). Youkai manage to go one step further than humans in all these pursuits because they adhere to magical theories―they take the unscientific approach of utilizing the unknown without attempting to unravel its mysteries. The acts of youkai may seem outdated, steeped in myth, or even outright wrong, but the truth is that they've simply transcended the scope of human understanding. Perhaps the most extreme example of this can be seen with the Lunarians from the Lunar Capital. The youkai of Gensokyo have their own currency and an economy that encourages free trade. What sets it apart from human economies is how they price things. Even though Ability Cards cannot be taken by force, the coins needed to purchase them are obtained through battles of bullets. This implies that the prices of the cards are in some way based on their effectiveness in battles. Considering how battles of bullets are essentially just a game, youkai probably think of their economy as a game, too. However, it undoubtedly succeeds at the main point of an economy―providing a low-risk means of obtaining things without having to resort to theft or violence. In this way, it's similar to the Spell Card Rules... in fact, they're probably related. Markets are battlefields, so someone will inevitably try to dominate them. Kappa and yamawaro are often thought of as mercantile youkai, but that undersells their prowess as economic strategists. Whenever new and complex rules are introduced, they are always the first to understand and exploit them, sometimes disrupting the entire market in the process. It's a dance of judging prices and juggling numbers, where you're free to choose to be happy with what you have or gobble up everything you can before it's too late. Success is not determined by hard and fast guidelines but by free spirits running rampant. The black markets were a youkai game that was supposed to settle down after the market god directed a human to investigate them. However, it probably didn't take much for the conflict to get drawn out because it was never really about the money―it's a clash between spirits and egos.
